Underarm Sweating (Hyperhidrosis) Treatment in Gangnam, Seoul
Botox injections into the underarm significantly reduce excessive sweating by temporarily blocking the nerve signals that trigger sweat glands — with results that last far longer than facial Botox.
Real Relief From Excessive Underarm Sweating
Hyperhidrosis is excessive sweating beyond what's needed to regulate body temperature — for the underarms, this can mean visible sweat marks and discomfort regardless of temperature, activity level, or antiperspirant use. It's a common, medically recognized condition, not simply a matter of hygiene or fitness.
This treatment uses a grid of small injections across the underarm to temporarily block the nerve signals that activate sweat glands in the treated area. Because it works directly on the nerve-to-gland signal rather than trying to absorb or mask sweat, the reduction in sweating is substantial — many patients describe it as close to dry.
Unlike facial Botox areas, underarm sweat glands respond to treatment for a notably longer period, so most patients only need treatment two to three times per year to stay comfortable.

Your Session & Recovery Timeline
Your doctor may use a simple test to map the exact sweat-gland area, ensuring injections are placed precisely where they're needed.
Topical numbing is applied, then a grid of small injections is placed evenly across each underarm.
You can return to normal activities right away. Avoid strenuous exercise or saunas for 24 hours as a precaution.
The nerve-blocking effect gradually sets in, with most patients noticing a clear reduction in sweating within the first week.
As the effect gradually wears off, a follow-up session maintains your results — most patients need treatment two to three times per year.

Underarm Sweating Treatment — FAQ
How is this different from a stronger antiperspirant?
Antiperspirants work topically to block sweat ducts at the skin surface. This treatment works at the nerve level, blocking the signal that activates the sweat glands in the first place — which is why the reduction is typically much more noticeable.
Will I stop sweating everywhere?
No — the treatment only affects the sweat glands in the injected area. Your body's overall ability to regulate temperature through sweating elsewhere is not affected.
How soon will I notice a difference?
Most patients notice a clear reduction in sweating within the first week, with the full effect typically established by day 10–14.
How long do results last?
Results typically last 6–9 months — noticeably longer than facial Botox areas — so most patients only need treatment two to three times per year.
Is this covered by insurance?
Coverage varies and depends on your individual insurance plan and whether hyperhidrosis has been medically diagnosed. Our team can help you understand your options at consultation.
